An impulse is a force action over a period of time.
It’s D or B Because investigation is some tho ur studying or experiment to know the final result Most likely D it’s not a or c
Answer:
Explanation:
As per Ampere's law the magnetic field at the surface of the wire is given as
here we have
so we will have
now again we use same value of current but wire with double the diameter
so the magnetic field at the surface is given as
so we have
When rubbing two insulators together, electrons from one insulator will be transfered to the other. so the insulator that has just received electrons now has a negative charge as it has received more electrons (making it more negative) the insulator that has just lost electrons has just become positively charged. NEVER SAY THAT PROTONS HAVE BEEN TRANSEFERD.... EVER. ONLY ELECTORNS ARE TRANSFERED.
Acceleration is given by change in velocity divided by change in time, so his acceleration should just be (10-5)/5 which is [tex] \frac{5}{2} \frac{m}{s^{2}} [tex]
The driveway is 40 meters plus 225/4. You can do the math.
